“Overview
In the world of personal audio, the ultimate sound experience generally comes from custom molded in-ear monitors (CIEMs). In recent times, top of the line (TOTL) CIEMs have gone from 3-6 balanced armatures per side to 10 and even 12 BAs per side. The Kaiser 10 is an example of a 10 driver CIEM and has 10 individual drivers in each ear-piece – a pretty awesome piece of spatial...” --Loquah

Ok first of all I will be using my Sansa Clip as my source as I feel an iem should always be tested with portable sources. I paid $200AUD for them brand new, which is dirt-cheap by Australian standards. I do not believe in burn in, especially for armature drivers - owning and listening to many iems has shown me burn-in is just a mental phenomenon where the brain adjusts to a new sound...” --ProjectDenz

“I wonder why UERM is often disregarded when picking from $1000 range. I'm guessing that it's due to "only" having 3 drivers, versus having 8 drivers per side. I can say with confidence that driver number does not equal sound quality(for the most part). Another reason I see why UERM might not be picked is its sound sig. It's perfectly flat. Personally, I love this. Reference sound with...” --kimvictor

“I'm giving these a 4 based on sound quality alone. I'm a cheap headphone user; I've gone from cheap headphone to cheap headphone over the past decade or so. I started with the Skullcandy Ink'd headphones, moved onto the Sennheiser CX400s, then the Meelectronics M6 and M9, and finally, this. I've also tried the Klipsch S4's. I'm currently on my third pair of these because well, they're so damn...” --az060693

This is my very first pair of custom IEMs after trying almost all of the high end universal IEMs -- SE530, UE Super Fi 10, Etymotics etc. The sound of these UE11 Pros is superior in every way to all of the universal ones I had, but even more important they stay in my ear and provide a proper seal. Since my ear canals get very narrow, I found it very difficult to get any of my universals to...” --alyanm

You could check the specs on the noble web site.
Please be kind in your critics, as this is my first review ever, and that English is not my first language.
1) ordering
I purchased the 8c on the noble website. The website in itself is very well organized and the ordering process was quite straightforward. I chose a...” --John0405

I had owned the UE-10's before this for about 3 years. So upgrading to these was a huge improvement in my opinion. Very nice full sound, with improved frequency response from 20 Hz to 18,000 Hz. Bass is much more present on these but not too overly stated. Gorgeous build quality. Very happy with these In ear monitors, I also own the JH-16's and still love listening to these all the time on...” --Richard Devine

Synopsis: The Noble Audio 4C is a custom-fit in-ear monitor (ciem) characterized by a flat tuning with no peaks or dips from the lower bass to the lower treble range. This upgraded tuning eliminates the dip in frequency response found in the older model. The bass, while not boosted at all, has excellent extension , the mids are clear and the treble is flat until a lift in the upper range...” --Kunlun

Intro
Noble Audio is the new brain child of John Molton, who is known around these parts as the Wizard. Formerly of Heir Audio, his CIEM designs are usually his calling card. However, his initial universal-fit 4.Ai and 3.Ai, and 5 designs saw a...” --eke2k6
